Battery identification system, battery identification method, and non-transitory computer readable medium

A battery identification method comprising:

• measuring, by a meter, a magnetic field distribution on an outer surface of a battery, using a plurality of magnetic elements, with a sensing surface of a board of a sensor facing the outer surface along a third-axis direction orthogonal to both a first-axis direction and a second-axis direction orthogonal to the first-axis direction, the battery including a plurality of battery cells electrically connected to each other and arranged in the second-axis direction, the outer surface extending in the first-axis direction and the second-axis direction, the sensing surface extending in the first-axis direction and the second-axis direction, the plurality of magnetic elements being arranged, in or on the sensing surface, in at least one row or column along at least one of the first-axis direction and the second-axis direction;
• identifying, by a computer, a type of the battery by comparing the magnetic field distribution measured by the meter with a reference magnetic field distribution, with reference to reference data indicating the reference magnetic field distribution;
• and
• outputting, from the computer, information regarding the identified type of the battery, as battery information.

A non-transitory computer readable medium storing a battery identification program to cause a computer to execute operations, the operations comprising:

• acquiring measurement data that indicates a magnetic field distribution on an outer surface of a battery, the magnetic field distribution being measured using a plurality of magnetic elements, with a sensing surface of a board of a sensor facing the outer surface along a third-axis direction orthogonal to both a first-axis direction and a second-axis direction orthogonal to the first-axis direction, the battery including a plurality of battery cells electrically connected to each other and arranged in the second-axis direction, the outer surface extending in the first-axis direction and the second-axis direction, the sensing surface extending in the first-axis direction and the second-axis direction, the plurality of magnetic elements being arranged, in or on the sensing surface, in at least one row or column along at least one of the first-axis direction and the second-axis direction;
• identifying a type of the battery by comparing the magnetic field distribution on the outer surface with a reference magnetic field distribution, with reference to reference data indicating the reference magnetic field distribution;
• and
• outputting information regarding the identified type of the battery, as battery information.
